Problems solved by technology

They are reputed to be obscure and complicated, and there has been little experimental motivation to consider non-abelian topological phases.
This makes the information vulnerable.
If a disturbance in the environment changes the state of the particle, the information is lost forever.
All schemes for controlling decoherence must reach a very demanding and possibly unrealizable accuracy threshold to function.
In 2000, Freedman showed that some extraordinarily complicated local Hamiltonian H can be written down whose ground state is V. But this H is an existence theorem only, and is far too complicated to be the starting point for a physical realization.

General Description of Quantum Computing

[0030] Apparatus and methods according to the invention include identifying a first quantum state of a lattice having a quasi-particle disposed thereon, moving the quasi-particle within the lattice according to at least one predefined rule, identifying a second quantum state of the lattice after the quasi-particle has been moved, and determining a computational result based on the second quantum state of the lattice.

[0031] In accordance with the present invention, “realistic” microscopics can be provided for d-isotopy, wherein “realistic” refers to atoms and electrons, for example, as opposed to loops and curves. More particularly, realistic means physical degrees of freedom, with local interaction (the particles are nearby to each other and know of each other's presence). The interactions are potential energy costs of bringing atoms near each other. Existing physical relationships, such as van der waals forces, may be used, along with othe...

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The subject matter disclosed and claimed herein is related to the subject matter disclosed and claimed in U.S. patent applications Nos. [attorney docket MSFT-3874 (308856.01)], filed Jul. 30, 2004, [attorney docket MSFT-3933 (308857.01)], filed on even date herewith, and [attorney docket MSFT-3935 (308859.01)], filed on even date herewith. The disclosure of each of the above-referenced U.S. patent applications is incorporated herein in its entirety.FIELD OF THE INVENTION [0002] This invention relates in general to the field of quantum computing. More particularly, this invention relates to topological quantum computing. BACKGROUND OF THE INVENTION [0003] Since the discovery of the fractional quantum Hall effect in 1982, topological phases of electrons have been a subject of great interest. Many abelian topological phases have been discovered in the context of the quantum Hall regime. More recently, high-temperature superconductivity and...
